A method for producing an aluminum piston for an internal combustion engine, which piston is designed as a round skirt piston. In the region of the radially outer end faces of the piston pin bosses the piston skirt has skirt recesses extending in the direction of the piston axis. In order to be able, when using the piston, to produce skirt recesses that have any shape a piston blank is produced in a forging process using a forging die, which piston blank has inner faces that are complementary to the outer shape of the piston having skirt recesses and not-recessed regions of the piston skirt, and the piston blank can then be further machined to produce the aluminum piston.
